Right, but what's not obvious is... why would anyone, ever, limit the size of the queue? The users in the queue cost nothing. They aren't spamming login attempts, they're just waiting. It doesn't matter whether the queue is 20 users or 20,000 users. It's an ordered list. Spot opens up? Grab first person from queue. No spots available? Don't grab first person from queue. Doesn't matter how long the queue is. A longer queue costs a tiny bit more storage, but by "tiny" I mean "an 8086 with 640KB of memory could handle a 20,000 user queue".
they use the queue system to throttle the logins on the server. If they limit to 100 people per server in the queue then they can maintain how many people get in at a time.
